About our fire stopping in Rustington

Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We don’t hold a third-party fire-stopping installer certificate, and we won’t pretend otherwise. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. Most enquiries involve old intumescent sealant that has split away and openings found when ceilings come down for a refit, on joints between fire-resisting walls and floors, service gaps in risers and pipe penetrations. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Rustington is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Buildings in a smaller place such as Rustington that need fire-rated sealing are typically schools, care homes, surgeries, small offices and flats over shops. Around those penetrations, fire-rated sealant is installed if specified, with depth, backing and gap all as tested.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

How a job runs

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes a single visit for a short list of penetrations, or a phased programme for a whole building, and we clear our waste as we work. What matters most for a job in Rustington is a clear list of what needs doing, so send photographs of each area. A fixed quote follows.

  1. First we confirm the product and tested details named in the specification.
  2. Openings are measured and grouped by detail.
  3. Old or wrong materials are cut out.
  4. Mineral wool or other backing is fitted where required.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Getting the site ready

  • Send any specification or drawings in advance
  • Point out parking and an unloading spot
  • Move anything stored against the joints

Why deal with it now?

It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach and each detail can be checked as we go. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.

The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Fire stopping in Rustington: the local picture

The area within 2 miles of Rustington holds several hotels. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. The 2 miles around Rustington include nine care or nursing homes. Where new services have gone through compartment walls in a care setting, the gaps need the specified product. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail.

At a healthcare site like Zachary Merton Hospital, under half a mile south-east of Rustington, new services through compartment walls are a constant, and each needs the specified seal. Hotels like New Inn Hotel (1.2 miles south-west of Rustington) are refurbished in phases, and each phase can open up compartment walls.

Doing it in-house

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

After the work

Keep the joints in good shape with a few simple steps:

  • Foam or ordinary sealant is never a fire-seal repair
  • Include service cupboards in routine inspections
  • Ask the designer to confirm details early on refits
  • Get seals inspected before ceilings and boxing close

Store the specified product details somewhere the next contractor can find them. Anyone resealing later needs to know which product and detail were used.

Specify fire stopping early on refits, not as an afterthought. Details can then be picked to suit the actual pipes, cables and ducts, and installation follows the programme.

Common problems we fix in Rustington

A common fault is a product that was never fire-rated in the first place: expanding foam or a general-purpose sealant pushed into a gap to tidy it. The opening looks sealed but has no fire test evidence behind it.

These are often picked up first by site or facilities staff:

  • Non-fire-rated filler around services
  • Service penetrations left open after M&E works
  • Old intumescent sealant that has split away
  • Head-of-wall gaps with no fire seal

Industrial units on estates such as Rustington Trading Estate (0.5 miles north of Rustington) often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal.

Choosing a commercial sealant contractor

Different surfaces, different methods

Linear joints

Head-of-wall joints often have to absorb slab deflection. The specified product and backing for that movement are what goes in, along the full length of the run.

Risers and ceiling voids

Openings above suspended ceilings are easy to miss. We follow your schedule area by area and tell you about openings outside the list.
